The Chilly Morning Mystery
On a chilly autumn morning, the church clock chimed six times. Under the wooden porch of the Cozy Kitchen Bakery lived Chester, a cheerful chipmunk with chunky cheeks and a twitching nose. Chester loved the sweet smell of cinnamon buns, but his absolute favorite treat in the world was sharp cheddar cheese.
Inside the bakery, Chef Charlie was bustling around doing his morning chores. He wore a checkered apron with a giant patch on the front pocket. Chef Charlie chopped fresh apples, rolled pastry dough, and set a huge block of golden cheddar on the kitchen bench. "Today," Chef Charlie declared with a chuckle, "I shall bake my champion cheddar biscuits!"
Clue Log: Missing from the Counter!
Chef Charlie turned his back for ten seconds to check the chimney damper. When he turned back around, a hefty chunk of cheese had vanished into thin air!

The Kitchen Inspection
"Good grief!" shouted Chef Charlie, clutching his wooden spoon. "Who snatched my cheddar?" He marched across the checkers-pattern tile floor to check every latch and latchkey. The kitchen window was open just an inch. Outside on the birch branch, a pair of bluebirds chirped a loud warning.
Down on the porch bench sat Chester, calmly nibbling a hazelnut. Chef Charlie charged out the back screen door. "Chester!" accused the chef. "Did you creep in and pinch my prized cheese? Your cheeks look extra chunky today!" Chester gave a quick chirp of protest and shook his bushy tail. He was no cheese thief—or was he?

The Cheddar Trail
Chester leaped from the porch railing and pointed his tiny paw toward the garden patch. "Chit-chatter!" Chester chirped, scampering ahead. Chef Charlie leaned forward and gasped. Sticking to the wet gravel path were bright orange crumbs. Something had crunched the cheddar in a hurry, leaving a clear trail straight past the chicken coop!
They crept quietly toward an old wooden chest resting beneath the peach tree. Inside the shadowy chest sat Chloe, a fluffy calico kitten wearing a shiny silver bell collar. Chloe had the missing chunk of cheese between her front paws and was happily munching away without a care in the world!

A Cheerful Feast
Chef Charlie let out a hearty chuckle. "Well, bless my checkered apron! Chloe was the cheese champion all along!" The chef gently scooped up the kitten and carried her back into the warm kitchen. "I owe you an apology, Chester. You didn't snatch anything; you helped crack the case!"
To celebrate, Chef Charlie baked a brand new batch of warm cheddar crunch muffins. He set a saucer of milk for Chloe by the hearth, placed a golden muffin crumb plate on the porch for Chester, and poured himself a hot pitcher of spiced cider. Chester munched happily, thinking that teamwork was truly the sweetest treat of all.

Predicting: Before revealing Chapter 3, pause and ask: "Why might Chester's cheeks look chunky even if he didn't take the cheese?" (Chipmunks naturally store nuts).
•
Inferring: Why does Chef Charlie apologize to Chester? What lesson does the story convey about leaping to conclusions?
